TDBB: Earth's Guardian #4.
She came up through a drainage grate in the afternoon light, pushed the iron cover aside, and climbed into air that tasted like exhaust and wet stone.
Her feet hit the street and the screaming came back.
She breathed through it, chest slow, the way she did in sandstorms, and let the noise settle into the lower register she was learning to tolerate. Then she started walking east.
The industrial district was four blocks away. She had mapped it from underneath so thoroughly that the surface felt like a translation of something she already knew. Every building footprint was a weight she had read through bedrock -- dimensions before she reached the fence, equipment layout from vibration, weak points like bones in her own hand.
She stopped in front of the first facility and tilted her head.
Long, low, two storeys, concrete over a wide steel frame, machinery still running. Chain-link fence, posts in shallow footings her feet read in half a second. Loading dock on the eastern end, four heartbeats, end-of-shift loose. Cheap tobacco and something underneath -- acrid, petroleum-heavy, same as the discharge pipe she'd sealed last night.
She had sealed the pipe. The tanks were backing up. The waste system had been building pressure for hours.
The building still stood.
Toph rolled her neck until it cracked and walked to the fence.
She put her foot against a post and told the steel what to do. The chain-link peeled back in a slow curl, opening a gap wide enough to walk through. She crossed to the southern wall and pressed her bare sole against the concrete base.
Reading from inside was different from reading through thirty feet of earth. Here it was immediate -- rebar runs inside the walls, steel in concrete like bones in tissue, the structure's weight transmitting through her foot in a chord of stress and load and uneven distribution.
Retrofitted at least twice, new steel bolted over old, and the junctions between old and new were where the chord went off-key.
She found the first junction, high on the wall, and started there.
She didn't push the concrete. That was the common mistake -- earthbending as force. Force was easy. The trick was asking concrete to become something else, to stop being a wall and start being a controlled descent. Which meant understanding what the steel inside was doing and making it do something different.
She pulled the rebar sideways, bending the rods ninety degrees so they no longer supported the concrete above but redirected load laterally. The wall section groaned and sagged inward without falling.
She moved to the next junction and did it again. The building understood what was happening before the people inside did -- stress patterns shifting, load paths finding new routes, the whole thing settling incrementally inward in a way that was going to be loud.
The dock workers noticed on the third pull.
Heartbeats shifted -- easy rhythm spiking into the jagged pattern of people who had heard something wrong. Voices went up. She couldn't parse the words but she read the tone. One of them was on a radio.
She didn't have time for this.
Toph dropped into a low horse stance, both palms against the southern wall, and pushed her sense through the structure in a single pulse. Ground floor, six people. Upper level, four more. Basement near the tanks, two. Twelve people, three zones, and the building was already listing toward the void she'd opened.
Couldn't collapse it with them inside. She wanted reduced footprint, not a funeral pyre.
"Out," she muttered, though none of them could hear. "Everybody out, now."
They weren't moving fast enough. The dock workers still argued near the fence. The upper floor heartbeats had clustered in confusion rather than heading for the stairs.
Toph snarled and moved.
She ran along the southern wall, right palm dragging against concrete, her sense locked on the interior frame, and she pulled. The rebar responded like iron snakes waking from sleep, tearing free from concrete in whipping tendrils that punched through interior drywall and wrapped around waists, wrists, ankles. She felt their shock through the metal -- sudden constriction, panic, the desperate grab for balance as steel lifted them off their feet.
She didn't gentle it. She yanked.
The rebar whipped six people through the air in controlled arcs, launching them through gaps in the southern wall like stones from a sling. They hit the dirt yard in rolling tangles, steel releasing as they landed, coiling back into the wall's skeleton.
"Move!" Toph shouted at the dock workers staring at their coworkers in the dirt. "That was the easy part!"
She was already reaching for the upper floor.
Four heartbeats up there, separated -- two heading for a compromised stairwell, two frozen near an office window. She couldn't reach them with the southern wall rebar; the load paths she'd redirected had weakened that section too much.
Toph pivoted, left foot stamping down hard enough to crack the ground, and called steel from the roof.
Corrugated metal sheeting peeled upward, fasteners popping like gunshots as she tore the roof frame free. She shaped it into four long ribbons and drove them down through the ceiling, feeling them punch through insulation and drywall and find the heartbeats waiting.
Two tried to run. Steel caught their belts and lifted them straight up through the hole, suspending them ten feet in the air before Toph flung them outward in a wide arc toward the yard. They hit hard but rolling, steel releasing at the last moment to let them tumble.
The other two had frozen. Frozen targets were easier. Steel wrapped their torsos and walked them down the building's eastern face like a controlled rappel until their feet touched ground.
Toph felt the basement heartbeats -- two near the tanks, finally moving toward an egress door. Good. They'd get themselves out.
She turned back to the building, but she was already too late for subtlety.
The southern wall was failing faster than planned. The load redirections were cascading -- each failure forcing the next, the structure hunting for equilibrium and finding none. Thirty seconds to control the direction, maybe less.
Toph planted both feet, dropped into the deepest horse stance she'd held since the Earth Rumble, and slammed both palms against the concrete base.
She didn't feel the structure now. She was the structure -- sense expanding through every beam, every column, every ounce of rebar still holding together. The roof pressing down, the eastern wall buckling outward, the torsional twist where retrofit junctions sheared. Too much information, too many forces, and she held them all and told each where to go.
"Down," she growled through her teeth. "Not out. Down."
She liquefied bedrock beneath the northwest corner, letting it settle two feet lower than the southeast. The tilt changed, mass shifting, and she grabbed the main support column and twisted, forcing the steel inside to rotate fifteen degrees so the collapse vector pointed inward, toward the empty yard center, away from the fence and street beyond.
The column screamed. Concrete around it shattered in dust, and the building began to fold.
It was working. Messy, loud, but working -- collapsing into its own footprint, debris falling inward rather than spraying outward. She held the rotation with everything she had, thighs burning, arms shaking, her body a conduit for force channeling from earth up through the building's bones.
Then she felt them. Vehicles at the fence line -- three, heavy, engines running, doors opening. Boots on dirt. Heartbeats, six, eight, ten, spreading in a fan formation with the sharp rhythm of people ready for violence.
She couldn't turn around. Couldn't split her attention. The building was mid-collapse, column still rotating in her grip, and if she let go now the whole mass would tumble outward into the street and buildings beyond.
"Stop what you're doing!" Amplified voice, bullhorn, harsh and male, carrying the frequency of someone never told no by anyone who mattered. "Step away from the structure with your hands where we can see them!"
Toph didn't answer. Jaw locked, breath coming short through her nose, every ounce of focus on the final descent.
"I said step away! Final warning!"
"Little busy!" The words ground out through clenched teeth. "Also blind, so the hands thing is just rude!"
She felt their hesitation -- confusion, the moment where they processed that the small girl in green was holding up a two-storey building with her bare hands and talking back to a tactical unit. She used that moment to push the collapse another foot inward, roof finally giving way and crashing into the hollow center.
"She's not complying, sergeant," a higher voice. "She's taking the whole block down!"
"Stop her!"
Toph felt the guns come up before they fired. Felt the metal in their hands -- steel and polymer, rounds in magazines vibrating with potential energy. She wasn't sure what they were supposed to do, but she could metal bend them. If only she kept her hands free.
She didn't let go of the building just yet.
Toph stomped her right foot and raised a wall of stone from the yard behind her, six inches thick, four feet wide, angled to catch anything from the fence line.
The guns opened up.
The sound was overwhelming -- automatic fire, bolts cycling, supersonic rounds cutting air. She felt impacts against her stone wall in a staccato drumbeat, chips spraying, the slab cracking under concentrated fire. It wasn't enough. She hadn't had time to make it enough.
A single sharp line of displaced air cut through the chaos, and her sense tracked it in half a second -- the spin, the heat of propellant, the vector that would take it through her stone wall where concentrated fire had already spiderwebbed the surface.
Toph let go of the building and jumped sideways, a wall of dirt rising to cover her.
She felt the bullet shatter rock, felt fragments spray her back, felt the round itself deform slightly on impact and still carry through, singing its murderous note as it hit her left shoulder from behind with force that spun her halfway around and drove her to one knee in the dirt.
The pain was -- she didn't have words. White and red and metal, foreign object through muscle and scraping bone, her body trying to fold around it.
The building finished coming down.
A roar of concrete and steel, thunderclap of dust rolling outward in a wave she felt through the ground even as she felt nothing else, sense narrowing to her shoulder where something looming sat. The shockwave hit her back, and she swayed but didn't fall.
Silence, after. The ringing absence where the building had been.
She knelt in the dirt, right hand pressed to the ground for balance, left arm dangling, blood dripping from fingertips in a slow rhythm her feet read against the earth. She didn't stand. Wasn't sure she could breathe.
She pressed her right hand to the wound and felt it with her fingers, then with her sense, reading the object inside her tissue the way she read rebar in concrete. Small, dense, high-carbon, mushroomed at the tip. Lodged against bone but not through.
Hot.
She had been in enough fights to know when something required attention and when something required fury. This required both. But the fury was faster.
She stood up.
The tactical unit was still at the fence, ten of them, heartbeats carrying the rhythm of people who had watched a girl take a bullet and stand up anyway. She felt their guns -- empty, bolts locked back, magazines spent. They had unloaded everything into her wall and her back, and stood there with useless weapons while she turned to face them.
The guns were metal.
Empty or not, the guns were metal, and the tactical webbing on their vests was metal, and the rebar in the rubble behind her was metal, and she was not feeling patient.
She raised her right hand, and she pulled.
Guns tore from officers' grips and flew toward her in a screaming cloud of steel, magazines and bolts and barrels separating mid-air into component parts that swirled around her like a cyclone of jagged edges. She didn't stop there. Reached into the rubble and called every intact rebar piece, dozens of rods ripping free from concrete and joining the swarm, until she stood in the center of a maelstrom of metal that filled the air with a shrieking hum.
The officers froze. She felt their terror, adrenaline so sharp it almost masked her shoulder's pain, and she let them feel it for a long moment before she closed her fist.
The metal collapsed into a single dense sphere the size of a beach ball, every gun and every rod compressed into solid mass that hit the ground with a thud she felt through her feet. She kicked it, and it rolled toward the fence line, coming to rest at the sergeant's boots.
"Next time," she said, voice raw, "aim for something I can afford to lose."
The vehicle engines exploded as she turned away. The helicopter was above, rotors she'd been too focused to notice before, and she didn't care.
She walked to the yard's center, collapsed structure behind her and compressed metal in front, and found the spot where the discharge pipe ran down through old foundation into the sewer tunnel below.
She opened the street with one foot, concrete moving aside smoothly, and dropped into the gap and pulled the street closed above her head.
Underground, she moved south in the dark, right hand against her shoulder, the wound throbbing with deep, bone-adjacent pulse she read as serious but not critical. The bullet was still in there. She could feel it against bone, small and hot and entirely too sure of itself.
She found a limestone shelf in the deep tunnel and sat against it and put both hands on the floor and breathed.
Above, Gotham's helicopter circled the collapsed building, cameras recording the compressed metal heap and the ten officers with empty hands and the woman who had gone into the ground and not come back up.
In her shoulder, something the earth hadn't put there was making itself at home.
She was going to need to think about that.
